Overview
Every penetration through a fire wall or floor is a weak point where fire and smoke can spread. A firestop system restores the fire rating of the separating element at that penetration.
The system is chosen by penetrant (plastic pipe, steel pipe, cable bundle, duct), opening size and substrate, following the tested detail. Labelling each location helps inspection and maintenance.
